DEVICE FOR COATING PAPER AND OTHER MATERIAL W|TH WAX.

SPECIFICATION forming part of Letters Patent No. 346,870, dated August3, 1886.

Application filed June 92, 1886. Serial No. 205,918. (No model.)

To aZZ whom it may concern.-

Be 1t known that we, Isaac SHERoK and J OSEPH BATIG, Jr., of Fremont, inthe county of Sandusky and State of Ohio, have invented certain new anduseful Improvements in Devices for Coating Paper and other Materials;and we do hereby declare the following tobe a full, clear, and exactdescription of the invention, such as will enable others skilledin theart to which it appertains to make and use the same.

Our invention relates to an improvement in devices for coating paper andother materials with wax.

The object is to provide means forapplying the wax to the paper as soonas the paper is in a condition to receive it after its manufac-. ture.

A further object is to provide a simple and effective device forapplying the wax to and removing the superfluous wax from the paper.

XVith these ends in view our invention consists in certain features ofconstruction and combinations of parts, as will be hereinafterdescribed, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view of the waxing deviceand portion of a paper-mill in longitudinal section, and Fig. 2 is adetached view of the waxing-cylinder.

The device or devices for waxing the paper are intended to form, ineffect, an attachment to a paper-making machine, so that the paper, asit passes from the calender-rolls of the mill, may be coated and waxedbefore it is further handled.

The paper-mill is only partially represented in the drawings, as itforms no part of our present invention further than its locationrelatively to the waxing device.

A represents the paper as it leaves the cal ender-rolls cc of thepaper-mill, and is drawn by a pair of synchronouslygeared rolls, B,beneath the waxing-cylinder O; or the paper might be led beneath thewaxing-cylinder while on or just leaving the gauze or blanket. Thecylinder 0 is hollow, and is provided either with trunnions 0, one orboth of which are hollow and loosely mounted on a hollow shaft, D,extending through the ends of the cylinder, or the cylinder may beprovided with one solid journal mounted in a suitable bearing at one endand mounted on a hollow shaft or pipe at at the opposite end.

The shaft or pipe D may either extend entirely or partially within thecylinder, or it may simply enter one of the'hollow trunnions. If itextends through the cylinder, it is provide with a series of openings,(1, within the cylinder, through which the melted paraffine or other waxis fed to the interior of the cylinder, and if stopped short at the endof the cylinder its end is left open to feed the melted wax into thecylinder.

The feed-pipe D leads from a supply tank or reservoir, E, in which themelted wax is held, to the cylinder 0, as above described, and isprovided with a stop-cock, d, to regulate the flow. The supply tank orreservoir may either be located above the waxing-cylinder 0, and the waxbe fed thereto by gravity, or it may be forced from the supply-tank intothe cylinder.

The cylinder 0 has a band-pulley or pinion, a, secured to one of itstrunnions or to asleeve or journal attached thereto, by means of which arotary motion is imparted to the cylinder from a drive-wheel. (Notshown.) The cylinder is covered with a soft porous material,

F-felt, for example-adapted to distribute the wax evenly over thesurface of the cylinder as it is fed through perforations f in itsshell. The curved shell of the cylinder may be formed of staves andcrevices left between them for the passage of the wax, or it may beformed solid and perforations formed in it, or the staves might be setclosely together and perforated.

The wax is forced outwardly through the perforations in thecylinder-shell by the cen trifugal force of the revolving cylinder, andit is obvious that the greater the centrifugal force the greater will bethe amount of wax fed to the surface of the cylinder; hence theregulating of the speed of the cylinder becomes an effective means forregulating the amount of wax deposited upon the paper, the travel of thepaper remaining uniform. One or more perforations or valves, S, areprovided in the end of the cylinder to supply air.

A pair of small rollers, G, are located in positions to hold thepaper'in contact with the face of the cylinder 0, and a jacket orshield,

. cylinder, and after passing over the roller K the paper passesdownwardly between a pair of stripping and smoothing pads, L. The padsmay be made of soapstone, or any mate rial which is a conductor of heat,and are faced with felt or its equivalent, and heated in any well-knownor approved manner.

The synchronouslygeared rolls B, above rc-. ferred to, are locatedbeneath the pads L, and serve to draw the paper from the calenderrollsinto contact with thewaXing-cylinder and stripping-pads, as described.From the rolls B the paper extends upwardly between another set ofsmoothing-pads, M, which are adapted to be adjusted toward and away fromeach other to regulate the tension of the paper; thence it passesbetween another set of syn chrononsly-geared rolls, N, and thence to awinding reel, 0.

Dripping-pans or wax-receptacles P are lo cated beneath the strippingand smoothing pads L and M, to catch the wax as it falls from the pads.The wax which is thrown from the surface of the cylinder 0 isconveniently conducted by the trough or troughs on the shield into oneof the receptacles P.

Thejacket or shield H may be a simple sheet of metal, or it may behollow and provided with radiating-coils to keep the wax on the face ofthe cylinder warm.

It is evident that slight changes might be resorted to in the form andarrangement of the several parts described without departing from thespirit and scope of our invention,- hence we do not wish to limitourselves strictly to the construction herein set forth; but,

Having fnllydeseribed our ixwention, what we claim as new, and desire tosecure by Letters Patent, is-

1. The combination, with a paper-making machine or mill, of a waxingdevice adapted to receive the paper directly from the calender-rolls,gauze, or blanket of the paper-making machine, substantially as setforth.

2. The combination, with a paper-making vrnachine or mill, of awaxing-cylinder located in convenient proximity thereto and feedingrollsadapted to draw the paper directly from the calender-rolls, gauze, orblanket of the paper-making machine or mill into contact with thewaxing-cylinder, substantially as set forth.

3. The combination, with a hollow perforated cylinder and means forrotating the same, of a pipe adapted to conduct melted wax from asupply-tank into the interior of the cylinder, an absorbent jacket on,the surface of the cylinder, and means for holding paper in contact withthe face of the cylinder, sub stantially as set forth.

4. The combination, with the rotary cylinder provided with a perforatedshell and the pipe adapted to conduct the melted wax into the cylinder,of the rolls adapted to hold the paper in contact with the cylinder andthe shield partially surrounding the cylinder and adapted to collect thewax thrown from the surface of the cylinder and convey it to a suitablereceptacle, snbstantiallyas set forth.

5. The combination, with the waxing-cylinder and the feed-rolls, of thestripping and smoothing pads and the wax-receptacles located beneaththem, substantially as set forth.

6. The waxing-cylinder consisting, essentially, of the perforatedcylindrical shell provided with an absorbent jacket, and having a hollowtrunnion for loosely mounting the cylinder on a feed-pipe, and airinlets or valves in its end or ends, substantially as set forth.

7. The combination, with the waxing-cylinder, its shield, and thefeed-rolls for drawing paper in contact with the cylinder, of thestripping and smoothing pads, one set being adjustable toward and awayfrom the paper, the roll for changing the direction of the paper, andthe receptacle for collecting the waste wax, the whole constructed andarranged substantial] y as set forth.

8. A waxing-eylindcr provided with perforations in its shell and adaptedto feed wax through the perforations by centrifugal force, substantiallyas set forth.

In testimony whereof we have signed this specification in the presenceof two subscribing witnesses.
